Nature, Humans, and other Bears. Possibly dogs (lead by humans).
They are, but black bears are more dangerous than grizzlies are.
Not sure what you're asking about here, but grizzlies are not invertebrates, they are vertebrates.
Grizzly bears populations in Yellowstone National Park have tripled in the last 30 years so I'm pretty sure that grizzlies are on the rise.
The fox is not a part of the diet of grizzly bears. Bears subsist mainly on berries, roots, and fish.
Grizzly bears never come into contact with black bears so the question is invalid. -------------- Of course grizzly bears come in contact with black bears. Grizzlies tend to inhabit more open areas, and black bears tends towards forested areas, but their ranges do overlap. Black bears evolved in the presence of grizzly bears due to their ability to climb trees, and their tendency to stay near mature forest trees. Black bears become more vulnerable to grizzly attacks when they venture too far into open grizzly territory, or when grizzlies explore black bear areas looking for food. This could occur after a forest fire creates an explosion of high calorie, ground cover and brush, for example. Grizzly predation on black bears occurred in Yellowstone Park at a number of sites: Hoodoo creek, Dave Adams Hill, Grizzly Overlook, and Pilgrim Creek. They took place from 1990 to 2005, indicating this is normal behaviour. The Grizzly Overlook attack is documented at http://www.nps.gov/yell/naturescience/upload/predation.pdf. There you will also find references to other incidents.
Alaska, Canada and Greenland There are no brown/grizzly bears in Greenland, but there are in the United States, Europe, and Asia.
Ursos arctos. Grizzlies are just an inland race of the brown bear.
